What tE3 (Duct In Thermistor Error) Means
tE3 indicates a Duct In Thermistor Error, per LG's Styler Help Library error-code list - the counterpart to tE1's duct-out sensor, this one monitoring the duct inlet temperature.
Common Causes of tE3 (Duct In Thermistor Error)
- Duct-in thermistor has failed or lost contact
- Sensor wiring fault
🔧 One Safe Check You Can Try
The unit will require a repair service, per LG's documentation.
⚠ Why You Shouldn't Go Further Than That
- As with tE1, this sensor sits inside the Styler's air-handling duct system, not a part accessible without disassembly, and LG's own guidance goes directly to service.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
